No matter what kind of day you're having, Prince George will always be here to left your spirits.
Whether it's re-watching his tricksy antics at various royal weddings over the years, or seeing the adorable snaps of him as a little baby back when his proud parents Prince William and Duchess Catherine were enjoying life as a small family-of-three.
But the latest instalment of Prince George might well take the cake (no pun intended) as he rings in his sixth birthday, because we've just been treated to three stunning new pictures of the young royal that'll literally melt your heart.
To mark his sixth birthday, Kensington Palace released the three candid snaps of the cheeky young royal.
The first was taken in the garden of their home at Kensington Palace in London recently.
In two other photos, George is seen wearing a white English football shirt and looking like he's having an absolute whale of time.
Just look at that cheeky grin! We can't believe how grown up he is now!
Proving once again she's a pro behind the lens, Duchess Catherine was the talent to capture these gorgeous shots.
Kate's already made a name for herself as the family photographer of choice, having captured numerous pictures of her children over the years which have been released for special milestones.
Earlier this year, Kate shared stunning new photos she'd taken of both Prince Louis and Princess Charlotte for their respective first and fourth birthdays.
If Kate's talent has told us anything other than the fact she's a dab hand behind the lens, it's that her children are growing up way too fast.
In June, the family-of-five stepped out at the annual Trooping The Colour parade, the first time they had attended the globally revered event together.
As expected, they were an absolute sight to behold, and Prince Louis (who made his grand balcony debut!) stole the show with his hilarious display of novel bemusement and frantic waving as thousands watched on.
Now, if the brand new birthday pictures are anything to go by, it looks like Prince George is already on the way to becoming the grown up young lad his dad and Prince Harry quickly became too.
We'll just be over here feeling nostalgic, and wishing the years would slow down!
